AXLE-LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 306,259, dated October'7, 1884. Application filed June 13, 1884. (Nomo'deL) To all whom it mayconcern:

Be it known that I, HENRY KELLER, of

Corpus Christi, in the county of Nueces and State of Texas, haveinvented a new and Improved AXle-Lubricator, of which the following is afull, clear, and exact description.

My invention relates to improvements in axlelubricators; and it consistsin the peculiar construction and arrangement of parts, as

y described, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate 1corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of my improved lubricatoras applied to an axle. Fig. 2 is a cross-section of the lubricator takenon the line a: 00, Fig. 1. Fig. 3

is a partly broken face view of the piston or plunger of the lubricator.Fig. 4. is a face view of the feed-wheel, and Fig. 5 is a sectional planview of the back end of the lubricator.

The letter A indicates the barrel or cylinder, which serves asa'reservoir for the oil or other lubricant to be fed to atrietion-bearingas. for instance, the arm I) of the axle B, on which avehicle-wheel runs. In the interior o chamber, 0, of the barrel A isheld centrally,

by suitable end bearings, the screw D, on

. which is placed by a threaded nut, e, the piston or plunger E, whichis fitted liquid-tight to the side walls of the chamber 0', so that noneof the oil can escape behind the piston. One end bearing of the screw Dconsists of a pin, d, which enters a recess in that end wall of thechamber 0, and at theother end the screw is journaled at d in theremovable end 40 cap or cover, F, and a collar, (Z fixed on the screwinside the cap F, holds the screw against endwise movement as it isturned by its fixed hand-wheel D to force the piston F out toward theaxle-arm b,.aud thereby force some 01 the oil 0 out into the channel Gopening into the end of the barrel A, and along said channel into thetube or pipe H, which passes through the axle-collar b, and'lies in acavity, h, of the axle-arm. The cap F is secured to the oil-barrel A byscrews f passing through side flanges, f, of the cap. This removable capF permits insertion of the piston E within the chamber 0 of barrel A,and access to the piston for repair or removal at any time required.There is a suitable opening, a, in the top of the barrel A, throughwhich the oil or other lubricant may be filled into the barrel, and saidopening has a screw or other cap, a, for tightly closing it. -Thelubricator is se cured to the vehicle-axle by a suitable strap or clip,J, which may at the same time serve to secure the tongue, hounds, orother part of the running-gear to the axle.

The operation is as follows: The lubricator being secured on the axle,the turned to carry the piston E back as far as it will go. The cap a isremoved and the lubricant is filled into the barrel and the cap againapplied. By reversing the motion of the screw D at any time required thepiston 7C E will be forced forward more or less, and will drive some ofthe lubricant before it through the passage G and pipe H to the exteriorsurface of the axle-arm b, and thus lubricate the bearing of thewheel-hub on the axle. I 7 5 open the channel G into thereservoir-chamber O at or near the top of the chamber, so that no oilwill flow therefrom except as it is forced out by the forward movementof the piston.

The size of the lubricator may vary. with the work required of it inoiling the axles of lighter or heavier vehicles, a single filling of thecup being intended to last for a long time, and the lubricator mayreceive any suitable 8 plain or ornamental finish.

The lubricator may also be used for oiling a large variety offriction-bearings, as will readily be understood.

Having thus described my invention, I claim 90 as new and desire tosecure by Letters Patent- The combination, with the barrel or reser voirA, its piston E, and screw D, of the pas sage G, leading from the top ofthe barrelchamber 0, and the tube H, passing through 95 the axle-collarb and into a cavity, 71., of the axle-arm b, substantially as shown andde scribed.
